Call_Control_Primitives

CC primitives (CCPs) are the communication between Layer 3 Port Control and Call Control Engine (CCE). The control and switching hardware in a system together with its operating firmware, the Xymphony, form the CCE. The CCE provides the functionality to initiate, manage and terminate calls through the interfaces in a Telesis system. In this communication, the required controls for call setup, call proceeding, and call ending occur free from the signaling type.

The decoding of CCPs is done according to the ITU-T Q.931 standard. Call modeling of all calls in Telesis systems is based on ISDN standards.

A call has two sides, one is incoming (or originating) side and the other is outgoing (or termination) side. During a call control, CCPs are sent from the CCE to Layer 3 and from Layer 3 to the CCE.

The CCPs are formed of Indications, Requests and Responses. CCPs define which algorithms or operations should be executed to set up, proceed or end calls; regardless of the port`s type or physical properties.

The decoded CCPs are detailed in ITU-T Q.931. Furthermore, Telesis also added some more primitives to make the monitoring and analysis complete such that:
